<p>how do you know if "of which" or "in which" is used correctly?</p>
<p>Here’s an easy way: move the preposition (“of” or “in”) to the end of the phrase, change “which” to “that,” and see whether it sounds correct.</p>

<p>“I hated Bob in the movie in which he appeared.” </p>
<p>“I hated Bob in the movie that he appeared in.” Looks good.</p>
<p>“That is something of which he should be proud.”</p>
<p>“That is something that he should be proud of.” Looks good.</p>
